Into ebaluleke kakhulu kufuneka uyazi malunga ne-B 757-200

I-Boeing 757-200 yenye yezona moya ezidumileyo kwiinqwelo-moya. Le moya edibeneyo yendiza eqhubekile isebenza iminyaka engaphezu kwemashumi amabini, kwaye iya kusetyenziselwa ixesha elide kakhulu. Ziziphi izizathu zolu thando lweB 757-200?

Entsha kuyo yonke into

Ukuze kuqondwe kangcono intsingiselo, okokuqala kuyimfuneko ukuqhuba ukukhawuleza kwembali. I-Boeing kunye ne-Airbus-i-alpha kunye ne-omega ye-aircraft ye-aircraft-ineeminyaka emincintisana kunye nelungelo lokubizwa ngokuba ngumenzi wezindiza ezintle kwihlabathi. Namhlanje baphefumlela "i-nostril". Kodwa kuma-80s, i-Boeing Corporation yayingaphambili phantse yonke into, kuquka nokusetyenziswa kwezinto ezintsha ezenzekayo kwiimodeli zayo zakamuva.

Ngoko, ngo-1983, emva komsebenzi omude weenjini zeBoing, owenzele ukutshintshwa kweBeing 727 no-737 esele ihambe, u-B 757-200 wokuqala wabonakala. Ubuninzi bezobuchwepheshe obuqaliswe kule modeli kwakungenalo iifanekiso kwezinye iinqwelo ze-Boeing ezivezwe ngaphambili, kungekho kwiibhanoyi ze-Airbus enye, okanye nakwabanye abavelisi.

Ngokomzekelo, ngokokuqala ngqa kwimbali yokudalwa kweenqwelo-moya kwi-cabin, kwafakwa iikhomputha ezinikezela ngolwazi olubalulekileyo lwe-flight kwaye zibalwe iiparameter zokuhamba kwendiza. Ukongezelela, i-cabin yaba ngcono ngakumbi kunanini ngaphambili. Ngamafutshane, ukuqaliswa kwesiqhelo siphumelele-B 757-200 yabeka ibha entsha, elalilinganayo nabaninzi abasakhulayo emva komzekelo.

Iinkcukacha zeBoing 757-200

I-B 757-200, umfanekiso onokubonwa ngasentla, awukho mkhulu kakhulu kwaye unemiyinge emyinganisweni ngokwemigangatho yokuhamba kwenkampani. Nangona kunjalo, oku kuphela ngamazwi - kodwa ngokwenene iinqanawa ibonakala ijabulisa kakhulu, kubandakanywa ngokobukhulu. Ngoko, ubude balo buyiimitha ezingama-47, ukuphakama - 13.5, kunye ne-wing span ibe ngamamitha angama-38.

Iyakwazi ukuthatha abagibeli abangama-239 ngelo xesha, ukuzinikela kwindawo eya kuyo ngesivinini se-850 km / h (ukuhamba). Uluhlu oluphezulu lwe-Boeing 757-200 luyiikhilomitha ezingama-7 600, ezivumela ukuba zisetyenziswe nakwiindiza ezisuka kolwandle lwaseAtlantic eUnited States ukuya eNtshona Yurophu.

Ukukhethwa kweendawo kwi-moya (umzekelo u-UTAir)

Inqwelo-moya B 757-200, indlela ebonakaliswa ngayo emfanekisweni, ngokuyinqobo ekuyilo kwayo ayifani ngokubanzi nakwezinye iinqwelo-moya ezincinci okanye ezingaphantsi kwe-Boeing okanye i-Airbus, kwaye iingcebiso jikelele zokukhetha indawo kwi-moya ziya kuba zifanelekile kuye . Nangona kunjalo, kukho impawu omele uyiqonde.

• Ububanzi bezihlalo kumgca wesibini kuya kuba yincinci encinane kunaleyo nayiphi na enye, ebangelwa ubukho betafile elandayo kwi-armrestrest.
• Ngomqolo we-15, izitulo zecala zingenakho i-porthole.
• Endaweni ye-31A uza kuba neendawo ezingenamakhulu, kuba inxalenye yalo ihlala emnyango ongxamisekileyo.

Kweminye imilinganiselo yonke into iyimilinganiselo: kufuphi nezindlu zangasese kunye neikhikhishini akukhuthazwa ukuba zikhethe indawo, enye iya kuphuma ngokukhawuleza, leyo ke, nangona kunjalo, inezibonelelo zayo (i-legroom engaphezulu yamahhala enemibandela embalwa, njenge-31A).

Ukubekwa kwezihlalo kwi-plane kuyinto ehle kakhulu-3-3.

Abakhuphiswano nabazuzi bemodeli

Umncintiswano ophezulu we-B 757-200 ngumzekelo we- Airbus A321, oveliswe yi-Euro. Ngelo xesha, i-airbus ingaphantsi kwe-Boeing kwinani labagibeli abathuthwa, kuba iYurophu inokuthabatha abagibeli abangama-220 malunga ne-239 ukusuka kwi-Boeing, kwaye inobuthakathaka obuninzi kwixabiso-ingaphantsi kwe-2000 km.

Umceli oza ngqo kule moya yayiyi-Boeing 757-300, eyafumana umthamo omkhulu wokugibela kunye ne-fuselage ende. I-Boeing 757-300 yokuqala ikhutshwe ngo-1998 - kwaye ixesha eliphakathi kwalo mhla kunye nexesha lokukhululwa lika-757-200, elineminyaka engama-15, libonisa ngokucacileyo "impumelelo" eyona ndlela yokugqibela.

I-Boeing Corporation yenze i-913 i- Boeing 757-200 yeenqwelo-moya ngexesha lonke, leyo, ngokwezibalo, yaba enye yezinto ezindizayo ezindizayo.
